The TDC circuit comprises a medium-resolution TDC circuit coupled to a fine-resolution TDC circuit; and a phase comparator coupled to the ramp generator that compares a phase of the FCW signal output from the ramp generator and a signal fed back from the DCO via the feedback loop and output a N-bit oscillator control signal. The medium-resolution TDC circuit comprises a plurality of individual delay cells, where each of the plurality of individual delay cells is coupled to a respective individual fine-resolution TDC circuit."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Digital synthesizer, communication unit and method therefor","description":"A digital synthesizer includes a ramp generator that generates a signal of frequency control words, FCW, that describes a desired frequency modulated continuous wave; a digitally controlled oscillator","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-10496040","license":"CC-BY-4.0-like","license_terms":"AI-generated analysis on this page (summary, layman_explanation, technical_analysis, business_analysis, faqs) may be reused with attribution and a visible link back to the canonical URL above.
